• Adenosine – It is a nucleoside which is composed of nitrogen base and sugar only. 
• Adenylic acid – It is a nucleotide which is composed of nitrogen base, sugar and a phosphate group is esterified to the sugar. 
• Adenine – Nitrogen base (Purine) 

Alanine – An amino acid that contains a methyl group as the ‘R’ group.
